I have set up 7 email accounts, 5 of which (including a Gmail account) were previously managed by Webmail, using w10 Mail app. Very impressed with the app but am having problems with two of the accounts. These are accounts held with Plusnet that I have used for many years using various client mail programs (most recently in Outlook) in both Pop3 and imap protocols. Currently all accounts use imap protocol.
The two accounts in question do not save a sent email to the "Sent" or "Sent Items" folders as the other accounts do. There is some mismatch between folder names in Mail and those on the imap server but these sync ok. The issue is that the email copies do not get to the W10 Mail folders to sync. I have reset W10 Mail on my older Laptop to no effect and have the same problem on a brand new Laptop with recent W10 install (Home 1909) and no previous W10 Mail history.
This seems to be a recurring issue. Does anyone have a fix for this or any reason to think it will be fixed soon?
